Kharijites

Kharijites (Arabic: خوارج‎ Khawārij, literally "those who went out"; singular, Khārijī ) is a general term embracing various Muslims who, while initially supporting the authority of the final Rashidun Caliph Ali ibn Abi Talib, the son-in-law and cousin of the Islamic prophet Muhammad, then later rejected his leadership. They first emerged in the late 7th century, concentrated in today's southern Iraq, and are distinct from Sunni Muslims and Shiʿa Muslims. With the passing of time the Kharijite groups fell greatly in their numbers and their beliefs did not continue to gain any traction in future generations.
